Kristen Smith, 31, of Aurora, Colo., was originally charged with kidnapping in a complaint filed in U.S. District Court in Madison on Feb. 7, according to the release. She was arrested in West Branch, Iowa, on Feb. 6 and has been in custody there since her arrest.

Smith allegedly took 5-day-old Kayden Powell and left him behind an Iowa gas station, in freezing temperatures. He was found alive 29 hours later.

If convicted, Smith faces life in federal prison, according to the release.

Smith will be brought to Wisconsin by federal law enforcement officials this week, officials said. Her initial appearance is scheduled for Friday.
